A plasmolysed cell can be deplasmolysed by placing it in a. pure water or hypotonic solution b. hypertonic solution c. isotonic solution d. saturated solution.

Sure, here are the step by step solutions with LaTeX tags: 1. Definition of Deplasmolysis: The swelling up of a plasmolysed protoplast under the influence of hypotonic solution or water is called deplasmolysis. $\text{Deplasmolysis: }\text{Swelling up of a plasmolysed protoplast under the influence of hypotonic solution or water.}$ 2. Cause of Deplasmolysis: Deplasmolysis is due to endosmosis. $\text{Cause of Deplasmolysis: }\text{Endosmosis.}$ 3. Time frame for Deplasmolysis: Deplasmolysis is possible only immediately after plasmolysis otherwise the cell protoplast becomes permanently damaged. $\text{Time frame for Deplasmolysis: }\text{Immediate after plasmolysis, otherwise cell protoplast gets permanently damaged.}$ 4. Process of Deplasmolysis: During deplasmolysis, water diffuses into the protoplast. $\text{Process of Deplasmolysis: }\text{Water diffuses into the protoplast.}$ I hope this helps!
